We currently have a customer evaluating a system with 16 x 12Gb/s SAS
drives driven by an HBA. They have intentions of building systems with
24 bays and 24 SAS drives.
Maybe we are going about this all wrong and perhaps there is a smarter
way to do this....however....
The customer's software is based on FreeBSD/NAS4Free. This runs on
Proxmox VE as a VM.
The VM's conf file looks like this snippet:
virtio0: /dev/sda
virtio1: /dev/sdb
virtio2: /dev/sdc
virtio3: /dev/sdd
virtio4: /dev/sde
virtio5: /dev/sdf
virtio6: /dev/sdg
virtio7: /dev/sdh
This is to allow the software to see the drives in the GUI and also to
provide max performance....we think. We are also considering PCI
passthrough options to have the VM see the HBA card directly.
The FreeBSD system will then use these drives to create a zpool.
With a limit of 16 Virtio disks, it seems that we can't use this
approach to operate 24 disks.
Any suggestions? Any creative approaches to work around this problem?
Thanks.

I wonder where 16 VirtIO disk per VM isn't enough, at the moment I can't
really see an usecase were its necessary to use 16 different VirtIO
disks on a single virtual machine.

Are we still limited to 16 VIRTIO disks on the recent versions of
Proxmox VE 3.4?
Thanks.
